Hi!
Yes I do understand that I need to add the products to my site, but the way I want to add them / remove them to/from the customers cart is where I am thinking of the possibility of using the Squarespace API to accomplish this.
A link to the site is here: https://www.smarti.dev/smarti-configuration-tool
When entering the site, select a couple of floors, and select how many rooms there are for each floor and press the generate button.
What I am trying to accomplish is that when a user clicks on the "Add Component" button in a room and selects one, that item should be added to the cart. This should also work for removing the item and updating the amount.
Thanks!
